Fields of application: THz-Time-Domain Spectroscopy Detecting & characterizing materials Using amplitude and phase information Analysing chemicals in powder and tablet form Analysing liquids and gases Investigating moisture distributions Distinguishing crystalline and amorphous structures THz-Imaging Identifying flaws and cavities in non-electrically conductive components Non-destructive testing (NDT) Identifying substances even through plastic pipes and tubes and other packaging Determining the layer thicknesses of multi-layer systems
Operation Principle Terahertz waves essentially stand for the frequency range of the electromagnetic spectrum ranging between 0.1 THz and 10 THz. Numerous non-conductive materials such as plastics or PVC, compounds, ceramics, paper or clothing appear almost transparent on THz frequencies. Substances such as drugs, explosives, pharmaceuticals, etc. display characteristic absorption properties within this spectral region. Figure 1: Schematic representation of wavelengths and frequencies These absorption properties act as a spectroscopic fingerprint and can serve to identify the substances concerned, even if these are hidden, for example in a letter.
T-SPECTRALYZER T/R/F MATERIAL ANALYSIS AND CONTACT-FREE INSPECTION The mobile T-SPECTRALYZER T/R/F series was designed for quick set-up and for routine measurements in everyday analysis tasks. Only a main connection is required to make the system ready to use without further infrastructure. Due to latest technology, the terahertz spectrometer does not require any additional cooling or external gas supply. This ensures a cost-effective operation. Individual expansion modules and an intuitive user interface support recording, processing and exporting your measurement results. Thanks to the touchscreen based user-friendly operation no time-consuming and costly training is required. As terahertz waves are completely safe, no expensive safety precautions are necessary. Within a few seconds the non-destructive and contact-free analysis of your samples is done. Full automation of your measurement process allows for extensive data sets to be taken with minimal high personnel costs. Its standardized hardware and software interfaces seamlessly integrate the spectrometer into your existing network and process flow.
